HEADLIGHT Application flied May 15,

T o all whom 'may concern Be it known that I, Louis FJ GEiLs, a citizen of the United States, 'residing at Chicago, in the county of Cook and State of Illinois, have invented "certain new and useful Improvements in Headlight Deiectors; and I do-hereby declare the following to be a full, clear,' and exact description of the invention, such as willfenable others skilled in .the art to which it appertains to make and use thevsame.

The present invention rela-tes to a light deflector for use with thehead lamps of' motorvehicles, andaims t'o provide a novel and improved vdevice ofthat kind which Vwill so deiect the light raysand restrict the projection thereof from the lamp, las to Vkeep the lightionthe roa'd ahead, andv to avoid glaring light which is apt Vto blindv or impair the vision of pedestrians and.0pcraters-of other vehicles.

Another objectisthe provision'of a deflector to be disposed' across a portion lof the lens or glass ofthe lamp casing, for deflecting the light rays back ,to lthe re-` flector, so as to Apass out through the funcovered portion of saidlens or` glass, whereby the light .is directed downwardly' toward the road, with a minimum amount of light directed above the` horizontal plane of the lamp. L

A further object is the provision of such a defiector having a colored window for the. passage oflight rays forwardly in the axis of the lamp casing, for the color effect, and to also penetrate fog, as well as directing a colored beam or pencil of light substantially horizontally from the lamp-to project a further distance from the vehicle, without producing an objectionable glare, and to enable objects for4 a considerable distance ahead to be observed, while the greater portion ofthe light/is directed downwardly on the road a short distance ahead of the vehicle. f

A still further object ofthe invention is the provision of a shield for the lamp bulb or source of light, which can bepositioned for restricting the passage of the light rays from the bulb through the uncovered por-l tion of the lens or glass of the lamp casing, such Shield being supported from the deflec tor in a novel manner.

Vith the foregoing and other objects in view, which will be apparent as the de` seription proceeds, the invention resides in' DEFLECTOR.

-the'construction and arrangement of parts, a "as hereinafter described and claimedit being understood that changes can be made within the" scope of what is claimed, without departing from the .spirit ofA the invention.

The invention is illustrated lin the i' ac-` companying drawing, wherein- Figure l is a front VView of a headlight lamp casing showing the de flector installed therein.` f

The delectory is intended for Vpractice. The lamp bulb 'or source of light f8 isl located v within the reflector afs usual,

and with an ordinary lens or 'glass 9,7 the light rays are directed forwardly in a ibeam whichincreases in width andheight, therebyspreading'the light downwardly, side-v vwise andupwardly, resulting 'in 4consider-1 able glare,A as well Vknown without lengthy discussion. Y

In carrying out the invention, therej is rprovided an opaque deflectorplate 11' of use in the vheadlight lamp casing of a motor vehicle, including .the parabolic reflector 7,7andfthe lens orglass panel 9 disposed across the suitable sheet metal which is substantially semi-circular vin shape, `jand 'wliichfis :dis-

. posed across the lower half or portion of thelensor lpanel 9, the convex edge of the plate 11 being clamped between the rim of the reflector 7 land the panel or lens 9. The plate' is slit near the ends 0f saidconveX edge,` to provide the sharp spurs or` points 12A whichcanbe bent slightly rearward,l so yas to bite the edge of the reflector 7 for holding Ytheplate l1 in place, or said points` may engage Aa washer or a f elt or similar ring which is sometimes inserted between the rim of the reflectorv and the lens ,or glass (not shown). f

lheldeets Plat-e $11 revest; the

, forwardly to a. considerable distance,"with' outproducing a glare that will be objections"l able to persons in front of the vehicle. This colored window alsoadds` to the distinctiveness and effect of the light directed from thefy lighty rays from-passing through the lower portion of the panel 9, and the rear surface of said plate is polished or otherwise fin' ished, so as to defiect the light rays back Vto the reflector 7 from which they are reflected upwardly and thence forwardly and downwardly by the upper portion of the reflector n to pass through the panel 9 above the plate 11 with those `rays. which pass upwardly from the bulb 8 to strike the upper portion of the reflector. In this way, most of the light rays all reach the upper portion of the reflector 7, from` which they are reflected forwardly and downwardly through the upper uncovered portionofthe panel 9, to beiV directed down to the road, thereby keeping v the light down low, and preventingy objectionable glaring.

The plate 11 is provided cent-rally of its upper edge with a raised portion 13 havingA an opening ;1 4 concentric with the lamp bulb r lamp. As shown, the panel 15 is` secured t0 the rear face of the plate 11 by means of lugs orears 1G extending from the edge of the opening 14 through saidpanel' and bent.A back'against said panel away from the opens shield 17 is disposed over or adjacent to the lamp bulbl 8, in order to restrict or prevent the passage of light rays from theybulb vstraight out through the uncovered .upper v portion of the panel 9. This shield 17 is of sheetl metal4 and is Vof fiat arched form, to be disposed yover the bulb 8 in a substantially vertical plane, and can be positionedto properly serve itsoffice. j

lThe shield 17 is support-ed fromthe deflector plate 11, and, for this purpose, the shield 17. is provided at its opposite ends with portions 18 bent to project forwardly and having the outstruck straps 19. ,Sup-A porting arms or brackets Q0 projectv from the opposite edges of the portion 13 of. the plate 11, and are bent to project rearwardly, and the rear terminals of said arms 20 are inserted through thestraps 19, thereby supporting the shield 17 for forward and rearward sliding adjustments ron said arms. When the shield has been properly adjusted and positioned, the adj'ustment'is made peras a unit with said plate.` ,being of .sheet metal is opaque, to prevent the light rays from passing'l from the bulb ...isfclaimed as'new is l device vof Ethe y Vcomprising a deflectorplate adapted to be manent by clamping or clinching the straps 19 and arms 20'together. This will tend to `bend or flatten out the straps 19, as seen in Fig, so 'as' to kink the arms 20, which will prevent the shield 17 from being adjusted accidentally or displaced from its proper lpositionk with reference to the defiector plate 11 and bulbV S The shield being connected to the deflector plate is applied and removed The shield 17 or sourceof light 8 upwardly in such a directiona's to leave casingin an upward path,

asmight produce an objectionable glare.

" Having thus described the invention,lwhat positioned in the mouth of thereflector of a lamp casing to cover one portiononly of the mouth of the'V reflector andto leave the other f portion uncovered, 'said y plate having a portion extending therefrom to be disposed directly infront of ythesource of light in the reflector, saidy portion having an yopening for thedirect forward passage of light ravsjanda colored panel carried by said plate' and disposed.v across said opening.
